Crash Team Racing Demo cheat for Spyro 2: Riptos Rage

This is spelled out in the "Ripto's Rage" instuction book, but not the "Gateway to Glimmer" version: There's a "Crash Team Racing" demo hidden inside Spyro 2. You can access the demo by pressing and holding L1 and R2, then press the "square" button simultaneously while in the intro menu screen.
